Description
Technical field
Experimental instrument field is the utility model is related to, specifically a kind of big volume colorimetric cylinder.
Background technology
Colorimetric cylinder is the key instrument for being used for visual colorimetric analysis experiment in chemical experiment；External form it is similar to common test tube but
An accurate graduation mark and it be furnished with rubber stopper or glass stopper more than test tube, and tube wall is thinner than common test tube.
But the colorimetric bore of 50mL and above volume is larger, i.e., cross-sectional area is too big, is very easy to determined
The problem of accuracy deficiency is caused during appearance, influence final testing result.
Utility model content
The purpose of this utility model is that solve deficiency present in existing colorimetric cylinder, there is provided a kind of more accurate big volume
Colorimetric cylinder
A kind of big volume colorimetric cylinder, it is characterised in that：Including body I, body II, graduation mark I, graduation mark II, long-neck, short
Neck and outer grinding port plug.
The body I is open at one end, the hollow cylinder structure of one end closure.
The body II, long-neck and short neck are open at both ends and interior hollow cylindrical shell structure.
The body I is identical with the size of body II.
The body I is connected with body II by short neck.The bottom opening of the open top connection pipe body II of the short neck,
The open top of the bottom opening connection pipe body I of the short neck.
The diameter of the long-neck and short neck is respectively less than the diameter of body I and body II.
The outer wall middle position of the short neck has portrayed graduation mark I.
The bottom opening of the open top connection long-neck of the body II.The open top of the long-neck is by outer grinding port plug
Closure, the open top inwall of the long-neck are provided with the interior ground mutually agreed with outer grinding port plug.
The outer wall of the long-neck is provided with graduation mark II.
It is from the bottom of body I to twice of the volume of graduation mark I from the bottom of body I to the volume of graduation mark II.
Further, the body I, body II, long-neck and short neck are formed in one structure.
Of the present utility model to have the technical effect that unquestionable, the utility model has advantages below：
The graduation mark of big volume volume half is located among short neck, and the graduation mark of big volume volume is located on long-neck, can be with
It is corresponding to reduce cross-sectional area, increase the accuracy of constant volume, lift the degree of accuracy and the precision of testing result.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model；
Fig. 2 is Fig. 1 plan；
In figure：Body I 1, body II 3, graduation mark I 2, graduation mark II 4, long-neck 6, short neck 7 and outer grinding port plug 5.
Embodiment
With reference to embodiment, the utility model is described in further detail, but should not be construed the above-mentioned master of the utility model
Topic scope is only limitted to following embodiments.It is common according to this area in the case where not departing from the above-mentioned technological thought of the utility model
Technological know-how and customary means, various replacements and change are made, all should be included in the scope of protection of the utility model.
As depicted in figs. 1 and 2, a kind of big volume colorimetric cylinder, it is characterised in that：Including body I 1, body II 3, graduation mark I
2nd, graduation mark II 4, long-neck 6, short neck 7 and outer grinding port plug 5.
The body I 1 is open at one end, the hollow cylinder structure of one end closure.
The body II 3, long-neck 6 and short neck 7 are open at both ends and interior hollow cylindrical shell structure.
The body I 1 is identical with the size of body II 3.
The body I 1 is connected with body II 3 by short neck 7.The bottom of the open top connection pipe body II 3 of the short neck 7
Opening, the open top of the bottom opening connection pipe body I 1 of the short neck 7.
The diameter of the long-neck 6 and short neck 7 is respectively less than the diameter of body I 1 and body II 3.The He of long-neck 6 in the present embodiment
The diameter of short neck 7 is equal；
The outer wall middle position of the short neck 7 has portrayed graduation mark I 2.
The bottom opening of the open top connection long-neck 6 of the body II 3.The open top of the long-neck 6 is by outer grinding port
Plug 5 blocks, and the open top inwall of the long-neck 6 is provided with the interior ground agreed with the phase of outer grinding port plug 5.
The outer wall of the long-neck 6 is provided with graduation mark II 4.
It is from the bottom of body I 1 to the two of the volume of graduation mark I 2 from the bottom of body I 1 to the volume of graduation mark II 4
Times.
The graduation mark II 4 is located at the middle lower end of the outer wall of long-neck 6.
The body I 1, body II 3, long-neck 6 and short neck 7 are formed in one structure.
The graduation mark of big volume volume half is arranged among short neck by the utility model, and the graduation mark of big volume volume is set
Put on long-neck, can accordingly reduce cross-sectional area, increase the accuracy of constant volume, lift the degree of accuracy and the precision of testing result
Degree.
